• php ffmpeg cannot save video to system temporary folder

  28 mai 2024, par user2818066

  I am trying to covert a video to h.264 format. I can save the new video to a normal directory but saving the new video to a Windows temp file fails. However I can manage to save a snapshot image from the video into Windows temp folder without problem. I cannot figure out what is the problem ?

  


  require_once(dirname(__FILE__).'/../vendor/autoload.php');

function get_ffmpeg_exe_path_arr_def(){ 
  return( array( 'ffmpeg.binaries'  => "C:/bin/ffmpeg.exe",
                 'ffprobe.binaries' => "C:/bin/ffmpeg.exe",
                 'timeout' => 3600000000, 'ffmpeg.threads' => 12
                )   )  ;  
}

$vid_inp = 'C:/Users/Jordan/Downloads/motorboat_org.mp4' ; 
$vid_out = 'C:/Users/Jordan/Downloads/motorboat_9.mp4' ;
$tmp_vid_out_file = tempnam(sys_get_temp_dir(), "Vid") ; //C:\Windows\Temp\VidA318.tmp 
$tmp_img_file = tempnam(sys_get_temp_dir(), "Img") ; //C:\Windows\Temp\ImgA234.tmp


$ffmpeg = FFMpeg\FFMpeg::create( get_ffmpeg_exe_path_arr_def() );
$video = $ffmpeg->open($vid_inp);
$format = new FFMpeg\Format\Video\X264('aac', 'libx264');

$video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(0.2))->save($tmp_img_file);
// Ok to save snapshot image to  C:\Windows\Temp\ImgA234.tmp 

$video->save($format, $vid_out); 
// This is ok to save video to  C:/Users/Jordan/Downloads/motorboat_9.mp4

$video->save($format, $tmp_vid_out_file); 
// This fails to save new video to   C:\Windows\Temp\VidA318.tmp

• How to save fluent-ffmpeg output to URL ?

  10 avril 2024, par volume one

  I am using fluent-ffmpeg to process videos and I want to save the final output file to a remote URL, not on the local server.

  


  Here is the code :

  


     ffmpeg('/path/to/file.mp4')
      .videoCodec(VideoCodec)
      .audioCodec(AudioCodec)
      .format('mp4')
      .output('http://localhost:8080/output.mp4') // This does not work at all
      .output('output.mp4') // this works but saves file locally which I'm not allowed to do
      .run();


  


  How can I save the file directly to a remote location (that is, without saving it locally) ? I know you can stream the output using pipe, but I cannot use streams because then ffpmeg will not set the duration value of the file.
